SCAFFOLDING FOR BUILDINGS AND THE LIKE.

I Specification of Letters Patent. Patented 061; 13, 1914.

Application filed December 1, 1911. 1 Serial No. 663,386. I

To all whom it may concern."

Be it known that I, EMIL Sonlinnn, a citizen of the Swiss Confederatlon, residing at Steinwiesstrasse 86, ,Zurich, Switzerland,

buildings, by use of whichupright poles are entirely dispensed with. t I v By use of the invention scaffolds can be strongly and securely erected in a very short time and entirely from the outside of the buildings. It is of great advantage when used in connection with buildings that abut footways or roads as by the absence of the poles no obstruction is caused. In carrying out my invention I provide a number of sockets which I build intothe external walls of a building placing them at regular intervals in vertical and horizontal rows the said sockets being adapted to receive and to sustain the endsof horizontal rails of brackets. The lower ends of the brackets abut against the wall or against brackets situated below and I place on three consecutive brackets arranged in vertical row a main; support carrying the platform for the workmen. I

In the accompanying drawings one mode of construction is shown by way of an example wherein:

Figure 1 shows a vertical section of'a wall with a number of superposed brackets carrying one main support secured in position. Fig. 2 shows a part of a staging in a ground plan. Fig. 3 shows theconnection of the main support with a bracket in a side elevation and Fig. 1 is a cross section thereof. Fig. 5 shows a bearer for planks in a side view and Fig. 6 in a front view. Fig. 7 is a side view of a socket with the end of the horizontal bar of a bracket inserted therein. Fig. 8 is a front view of the socket. Fig. 9 shows a device formaking a cement-socket in a wall in a side View. Fig. 10 is a cross section on line AB of Fig. 9. Figs. 11 and 12 show a collapsible bracket in two side views. Figs. 13-17 show details of construction. j

According to mv invention I place sockets 1 (Figs. 1, 2, 7 and 8) at suitablelevels and intervals and at right angles with the walls sothattheir months are flush with the wallsof the building. Each socket consists of a piece of iron with rectangular cross sec- "tion. In the front end of the socket is a circular opening 2 having two recesses 3 arranged opposite each other. The dimensions of the opening 2 are such that the free end 4: of the bracket with its noses 6 can be easily inserted. The recesses 3 are situated in a horizontal line when the socket 1 is correctly placed in the wall and the bracket -5 has to be turned through a right angle when it has to be taken out of the position shown in Fig. 1. The bracket 2 consists of a horizontal barbent at a'right angle at 8 the other end 4 has preferably a round cross section and noses 6 situated 1 opposite each other. The bracket comprises further a bar 5 rigidly fixed on th e horizontal bar and its other end is slightly bent and provided with an eye 7 through which the freeend 4 of any bracket may be insorted. To 'stifien the bracket a truss 5 is provided connecting the horizontal bar with the-bar 5 The free end of the bar 5 may be provided with a plate 21 (Fig. 1) when the bracket is to be used as the lowest one of a vertical row of brackets.

' The freeends 8 of thebrackets 5 extend upwardly. On each of the ends 8 an open collar 16 is placed having the form of a C. The free ends of the collars 16 embrace the flangesof a vertical bar 11 of'a main support..10. The bar 11 is of T shaped cross section the collars 16 embracing the flanges thereof; In one of the flanges of bar 11 cross pins 15 are fixed by means of which the main support rests on thecollars 16 and therebyon the brackets 5. To secure the collars 16 a pin 17 is removably fixed in the end 8 of each collar.

To the bar 11 a horizontal bar 12 is rigidly fixed. To suites the main support 10 a truss 13 is provided which is rigidly fixed to the bars 11 and 12.

To form. a platform suitable for executing work ledges 18 are placed on the bars 12 and on said ledges are placed hangers or bearers 19 two of which carry a cross bar 20. On the bars 12 and 20 boards are placed 55 -30 is provided with noses 31 for the pursockets 1 are apart.

three brackets wedges 21 may be used which can be driven between the-pins 15 and the collars 16.

By erecting a wall the sockets 1 are built into the wall in vertical rows in such distances apart that a bracket inserted in one socket reaches with its lower end the next lower socket 1 in such a manner that the eye 7 lies exactly over the bore of the socket. Taken for instance that the platform has to be raised to enable the bracket-layers to pro.- ceed with their work then a workman will stand on a boardlaid on the brackets 55. Then he will have to remove the pins 15 and lift the main support 10 for a distance which equals the distance for which two By raising the main support the latter enters a sleeve 16 of an upper bracket. He now fixes the pins 15. It has been found that the bracket would not aflord a safe platform for the workmen as the sockets 1 nearest to the workplace are in most cases in brickwork not yet dry, etc. Therefore it will be necessary to-distribute'the whole load over three or at least two brackets 1.

, maybe made of cement.

Instead of'having sockets of metal they I I may make a brick of cement or the like having an opening to receive the end of the bracket and I build the brick in the wall at the proper place in the usual manner. If sockets are to be inserted in walls already existing I make a hole in the same and I use a core shown in Figs. 9, 10 to form the opening for the bracket end in a block of cement with which the hole is filled. The core comprises a piece 44 of rectangular cross section and two pieces 42, 43 arranged on both sides of the piece 44. Each of the pieces 42, 43 is provided with a nose. By the c0nstruction of a socket a washer 46 is placed over the pieces 42, 43 and 44 and the whole device is placed in the hole of the wall which is then filled up with cement as shown. After a time when the cement has hardened the piece 44 is drawn out and after that the pieces 42, 43. The washer 46-remains in the opening and forms an abutment for the noses ofthe horizontal bars of the brackets. The mouth of the opening has an enlargement 47 adapted to receive a cover to hide the, opening.

Asshown in Figs. 11 and 12 the bracket may be made foldable. The horizontal bar pose described above. On to the bar 30 two members 34 and 35 are linked by means of pivots 32 and 33. The members 34, 35 are jointed by means of. a pin 36 which is removable .in the eyes of the two members 34, The pin is fixed to a chain which is attached to the member 35.

The connection of the member 34 and bar 30 may be made as shown in Figs. 13 and 14. The bar 30 is provided with a slot and the member 34 with a cross pin 41 which may pass through the slot. For mounting the bracket the pin 41 is passed through the slot and the member 34 turned through a right angle. The bar 30 rests on the members 34. The end of the bar 30 may be enlarged as shown in Fig. 2 and the opening of the socket adapted to receive the said end is shown at 40 in Fig. 17. The end of the horizontal bar may be bent as shown in Fig. 16 and the hole in the socket would have a corresponding slope. Also I have described the best way of executing my invention I can think of various details of construction can be altered without departing from the spirit of my invention.

What I claim is:

l. The combination with an outside wall of abuilding, of a plurality of superposed supporting brackets extending outwardly from said wall, a work supporting bracket extending vertically along said supporting bracket, collars for connecting said working bracket with said supporting brackets, and pins supporting said working bracket on said collars, substantially as described.

2. The combination with the outside wall of a building, of a plurality of superposed supporting brackets extending outwardly from said wall, said brackets having upwardly projecting ends, ring-like collars adapted to surround and be supported by said ends, a single scafiolding bracket extending vertically along said supporting brackets, and means for securing said scaffolding brackets to said collars.

3. The combination with the outside wall of a building, of a plurality of sockets therein arranged in superposed relatlon,

and superposed supporting brackets con- EMIL sonitiann.
